I use Evernote, and like it. (Mostly for to-do stuff, in a way I can tweak it in a way I like + sync with phone.) For the other alternate solution is text notes (in Markdown), which I use a lot (when I don't need to sync stuff + want to enjoy distraction-free environment without Internet). The only real annoyance of Evernote is that each time I click on an external link, it asks if I really want to leave Evernote (anxious attachment?).
